How Fan Convector Heaters Backup Heat for Heat Pumps, explained by an El Cajon air conditioning expert

 

Fan convector heater units are used as a main building heat source or as a backup heat source where a heat pump is installed (combining air conditioning and heating).

A hydronic heating coil, hot water heated by a hydronic heating boiler is used to warm air via a heat exchanger that is mounted in an air handler.  Pipes conduct hot water from the boiler to the heat exchanger and back to the boiler. The air handler blows building air from return registers and ducts into the air handler, across the heating coil, and on to supply ducts and registers.

Used in crawl spaces, garages, basements, or other locations where additional heat is required or where we want to add heat to a previously un-heated area, ceiling, wall, or floor mounted fan convector heating units are a convenient way to push warm air heat into a chilly or un-heated area by converting hot water heat produced by a heating boiler to warm air heat provided by a fan convector unit.

We often find an electric or hot water-heated convector unit mounted in crawl spaces or other building areas in freezing climates as a step to protect building plumbing from freeze-ups. Convector heaters suspended from the crawl space ceiling has to have nothing combustible or too close to the heater.  Make sure that your added heat source does not create a fire risk.

An electric ceiling mounted fan convector unit and similar fan convector heaters obtain their heat from hot water piped as a separate heating zone or as a loop off of an existing heating zone that is otherwise heated by a conventional hot water heating boiler or hydronic heating system fueled by heating oil, gas, a heat pump, or even solar heating.
